Proma

Proma is an open-source, general-purpose desktop agent app for macOS, Windows, and Linux, aimed at people who use agents heavily for work such as coding, writing slides, and research reports. It combines chat, agent, and planning modes with project workspaces, memory, an embedded browser and terminal, scheduled tasks, and file preview and editing in one window.

Its design centers on organizing context. Work is split into projects, each with its own AGENTS.md instructions, a memory index, and per-project skills and MCP servers, so an agent only sees the tools relevant to that project. Sessions handle one task each, and earlier sessions or files can be referenced by dragging them into the input box or with @ and &.

Sub-sessions run beside a main session as cleaner-context alternatives to subagents, for parallel research or adversarial review. Explore mode branches from a finished answer into any number of side explorations and then brings the results back into the main session. File changes are grouped by turn, shown as diffs for code, and tied to Git worktrees with a one-click terminal.

The open-source edition uses provider channels and API keys you configure yourself. Development has slowed in favor of a separate commercial edition that adds hosted model access, web search, team quotas, and organization-wide skill distribution.
